IPC: G11B7/00
Filed: 1988-06-30
Abstract: PURPOSE:To achieve a high density recording by changing the irradiating energy of a light beam according to an information signal to be recorded in multistage, making the condition of the light beam irradiated part of an information recording medium into the multistage and recording multiple information. CONSTITUTION:An information processing unit 10 converts the inputted information signal to plural levels, and the processed signals at plural levels are outputted to a semiconductor laser 11. The semiconductor laser 11 irradiates a laser beam for recording with the multistaged energy or wavelength according to the signals at plural levels which is outputted from the information processing unit 10. When the laser beam of such a multistaged optical characteristic is made to irradiate the recording layer of an information recording medium (optical disk) 20 through an optical system 30, the condition change according to the energy of the laser beam in the irradiated part is generated, and the multistaged information is recorded. Thus, the high density recording can be practically achieved.

Filed: 1989-06-28
Abstract: PURPOSE:To lighten the burden of a CPU and to improve the processing speed by executing automatically the data save at the time of switching a window by only new window write from the CPU. CONSTITUTION:At the time of switching windows B, A, an access signal is generated from a CPU and a control signal generating part 106 generates a strobe signal for read-out/write to memories 1, 2. The memory 1 reads out information of a designated address through an address generating part 107, gives it to an input A of an MPX 104, and simultaneously, it is read out of the memory 2, as well and given to an input B of an MPX 103. An input of the MPX 103 passes through a data processing part 105, written in the memory 1 by a signal of the control signal generating part 106, and an input of the MPX 104 is also written simultaneously in the memory 2. By repeating this processing, a data exchange in a superposed area of the windows A, B, namely, switching is executed. According to this constitution, at the time of switching the window, a part of data can be brought to save at a high speed by executing new window write, and the data recovery can also be executed at a high speed by lightening a load of a CPU, and the processing performance is improved.

Abstract: PURPOSE:To correctly detect a light position by a method wherein light position signals to indicate the position in the X direction and light position signals to indicate the position in the Y direction are so contrived as not to interfere with each other, and at the same time, the amount of light is controlled in such a way that the sum total of the light position signals in the X direction or the Y direction becomes constant. CONSTITUTION:Photocurrents IX+, IX-, IY+ and IY- which are outputted from each electrode 9-1, 9-2, 3-1 and 3-2 of a light position detecting element 1 are each converted into voltages V1-V4 by operational amplifiers 11a-11d for current-voltage conversion corresponding to the electrodes.

Title: Semiconductor relay circuit
Inventor: YAMAGUCHI SHUICHIRO
IPC: H03K17/78
Filed: 1986-07-14
Abstract: PURPOSE:To quickly charge the gate-substrate capacity of an output MOSFET by reducing the value of a resistor used to obtain the OFF bias of a driving FET of a depression mode in a transient period during which said gate-substrate capacity is charged. CONSTITUTION:When the gate-substrate capacity of an output MOSFET 4 is charged, the D (drain)-S (source) impedance of a driving FET 6 of an E (enhancement) mode drops. Then the gate-substrate capacity of the MOSFET 4 is quickly charged via the FET 6. Thus the gate-substrate voltage of the MOSFET 4 rises up and the both-terminal voltage of a resistor 3 drops. Therefore the D-S impedance of the FET 6 of the E mode rises up and the voltage is generated at both terminals of the resistor 3 by a slight current flowing through a driving FET 5 of a D (depression) mode. The FET 5 is kept under an OFF state by the voltage produced at both terminals of the resistor 3. Thus it is possible to reduce the level of a working current in a steady mode.
